@Rabe: What version of FF do you have? I tested it on 25.0.1. If you open up the web console (Ctrl+Shift+K), do you see any errors on the console?

@pythrr: I used the list of suggested names on the PlayerNames Wiki page here in Fumbbl except for Skavens and for the undeads. Skaven names coming from a method described in the Book of the Rat and for undead/necro names I got deep into the database of the Cyanide computer game Anyway, the full list of sources is included on the project site if you're interested ;]
